Variation of the electron flux spectrum along a solar flare loop as inferred from STIX hard X-ray observations

Anna Volpara, Paolo Massa, Sam Krucker +3

Regularized imaging spectroscopy was introduced for the construction of electron flux images at different energies from count visibilities recorded by the Reuven Ramaty High Energy…
